Semiconductor device, and method for manufacturing semiconductor device

摘要

A semiconductor device includes a substrate, a fuse that can be blown by the radiation of light formed above the substrate, and insulating films formed on the fuse and on the substrate. One of the insulating films includes a flat portion formed on the substrate and the surface thereof is higher than the surface of the fuse, and a protruded portion formed on the fuse continuously from the flat portion, and protruded from the surface of the flat portion.
